Description

Technical Field

[0001] This utility model relates to the field of television back cover technology, specifically to an extruded ultra-thin flat panel large-size television back cover. Background Technology

[0002] The back cover of a television is an important component. Located at the back of the television, it primarily serves to protect internal components, provide structural support, facilitate heat dissipation, and enhance aesthetics. Television back covers are typically made of metal, plastic, or wood.

[0003] Currently, most TV back covers on the market are injection molded, made primarily of PC+ABS blends, with a smaller number being vacuum-formed, primarily made of ABS. However, existing back covers are prone to deformation after processing. To reduce deformation, most manufacturers increase the thickness of the back cover, resulting in increased weight and making it difficult to use in large-screen models over 100 inches. Injection molds are expensive, and the amount of material used in injection molding is high, leading to high costs. Large-screen models are often assembled from multiple back covers, and deformation is a prominent issue regardless of size, especially for vacuum-formed back covers, which are prone to bulging and deformation. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an extruded ultra-thin flat panel large-size TV back cover.

[0005] The purpose of this utility model is achieved through the following technical solution: an extruded ultra-thin flat panel large-size TV back cover, including an extruded sheet, a power cover attached to one side of the extruded sheet, and an AV interface cover attached to one side of the extruded sheet. The extruded sheet is composed of two polycarbonate layers and a glass fiber reinforced PC layer sandwiched between the two polycarbonate layers. The other side of the extruded sheet is pressed with texture.

[0006] Preferably, the texture is a checkered pattern, vertical stripes, sandblasted texture, brushed texture, or triangular arrow pattern.

[0007] Preferably, the thickness of the extruded sheet is 0.6-2.0 mm.

[0008] Preferably, the extruded sheet has a first clearance through hole communicating with the power supply cover and a second clearance through hole communicating with the AV interface cover.

[0009] Preferably, the extruded sheet has first mounting grooves on both sides of its bottom, and the back cover of the ultra-thin flat panel large-size TV also includes a bracket plate fixedly connected to the inner wall of the first mounting groove, and the bracket plate has mounting holes for mounting the base.

[0010] Preferably, a U-shaped reinforcing plate is attached to the top of the extruded sheet near the first mounting groove.

[0011] Preferably, the back cover of the ultra-thin flat panel large-size TV also includes multiple fixing seats that are fixedly attached to one side of the extruded sheet, and buffer rubber pillars that are detachably connected to the fixing seats.

[0012] Preferably, the outer wall of the buffer rubber column is provided with an annular groove, one side of the fixing seat is provided with an arc-shaped slot, and the top of the fixing seat is provided with a clamping groove communicating with the arc-shaped slot. The buffer rubber column is engaged with the fixing seat through the arc-shaped slot and the clamping groove.

[0013] Preferably, the rear shell of the ultra-thin flat panel large-size TV also includes reinforcing ribs fixedly connected to one side of the extruded sheet.

[0014] The beneficial effects of this utility model are as follows: The ultra-thin flat panel large-size TV back cover of this utility model is made of extruded sheet material, a power cover attached to one side of the extruded sheet material, and an AV interface cover attached to one side of the extruded sheet material. The extruded sheet material is composed of two polycarbonate layers and a glass fiber reinforced PC layer sandwiched between the two polycarbonate layers. The use of the glass fiber reinforced PC layer improves the overall rigidity and strength of the extruded sheet material, effectively avoiding the problem of easy deformation after processing. It can produce a thinner and lighter back cover. Moreover, the extruded sheet material itself can be cut according to the size of the TV, adapting to more size models and saving injection molding costs. In addition, the two polycarbonate layers cover both sides of the glass fiber reinforced PC layer, avoiding the appearance of loose fibers in the glass fiber reinforced PC layer that affects the quality of the back cover. Furthermore, the other side of the extruded sheet material is pressed with texture, which is more conducive to improving the quality of the back cover and meeting the sensory needs of consumers.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] like Figure 1-4 As shown, an extruded ultra-thin flat panel large-size TV back cover includes an extruded sheet 3, a power cover 1 attached to one side of the extruded sheet 3, and an AV interface cover 2 attached to one side of the extruded sheet 3. The extruded sheet 3 is composed of two polycarbonate layers 31 and a glass fiber reinforced PC layer 32 sandwiched between the two polycarbonate layers 31. The other side of the extruded sheet 3 is pressed with a texture (not shown in the figure).

[0022] The extruded ultra-thin flat-panel large-size TV back cover uses an extruded sheet 3, a power cover 1 attached to one side of the extruded sheet 3, and an AV interface cover 2 attached to one side of the extruded sheet 3. The extruded sheet 3 consists of two polycarbonate layers 31 and a glass fiber reinforced PC layer 32 sandwiched between the two polycarbonate layers 31. The glass fiber reinforced PC layer 32 improves the overall rigidity and strength of the extruded sheet 3, effectively avoiding the problem of easy deformation after processing. It can produce a thinner and lighter back cover. The extruded sheet 3 itself can be cut according to the size of the TV, adapting to more size models and saving injection molding costs. The two polycarbonate layers 31 cover both sides of the glass fiber reinforced PC layer 32, avoiding the appearance of loose fibers in the glass fiber reinforced PC layer 32 that would affect the quality of the back cover. In addition, the other side of the extruded sheet 3 is pressed with texture, which is more conducive to improving the quality of the back cover and meeting the sensory needs of consumers. Furthermore, when assembling into a television set, one side of the extruded sheet 3 is the interior side of the television set, and the other side of the extruded sheet 3 is the back surface of the television set. The glass fiber reinforced PC layer 32 uses existing technology, with a glass fiber addition of 10wt%-30wt%, which significantly improves the rigidity and strength of the sheet. This is only used as an application example; for example, model 3025G30, 500R-131, or G-3110PH can be selected, with model 3025G30 being preferred.

[0023] Furthermore, the texture can be a checkered pattern, vertical stripes, sandblasted texture, brushed texture, or triangular arrow pattern. The texture can be pressed out using a corresponding texture roller according to customer requirements. Preferably, the texture is a checkered pattern.

[0024] Furthermore, the thickness of the extruded sheet 3 is 0.6-2.0mm, which is thinner and lighter than the traditional 30-50mm thick TV back cover; preferably, the thickness of the extruded sheet 3 is 1.4mm.

[0025] Furthermore, the extruded sheet 3 has a first clearance through hole 4 communicating with the power cover 1 and a second clearance through hole 5 communicating with the AV interface cover 2.

[0026] Furthermore, the extruded sheet 3 has first mounting grooves 6 on both sides of its bottom. The rear shell of the ultra-thin flat-panel large-size TV also includes a support plate 7 fixedly connected to the inner wall of the first mounting groove 6. The support plate 7 has mounting holes 8 for mounting the base. The mounting holes 8 of the support plate 7 facilitate subsequent assembly and fixing with the TV base.

[0027] Furthermore, a U-shaped reinforcing plate 9 is attached to the top of the extruded sheet 3 near the first mounting groove 6, which facilitates the improvement of the support force between the extruded sheet 3 and the bracket plate 7 when the extruded sheet 3 is assembled into a television set, and prevents the extruded sheet 3 from deforming.

[0028] Furthermore, the back cover of the ultra-thin flat-panel large-size TV also includes multiple fixing seats 10 that are fixedly attached to one side of the extruded sheet 3, and buffer rubber pillars 11 that are detachably connected to the fixing seats 10, which is beneficial for buffering and protecting the internal components of the assembled TV.

[0029] Furthermore, the outer wall of the buffer rubber column 11 is provided with an annular groove 12, the side of the fixing seat 10 is provided with an arc-shaped slot 13, and the top of the fixing seat 10 is provided with a clamping groove 14 that communicates with the arc-shaped slot 13. The buffer rubber column 11 is engaged with the fixing seat 10 through the arc-shaped slot 13 and the clamping groove 14.

[0030] Furthermore, the back cover of the ultra-thin flat panel large-size TV also includes a reinforcing rib 15 fixedly connected to one side of the extruded sheet 3.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
